A lot of IT has moved to MSPs. And MSPs care that their engineers are certified in the software or equipment their clients use. It's a selling point, because personnel are the product.

But if the job is working with Cisco network equipment and Windows PCs, a Google cert is worth less than the paper it's printed on. I don't know how many businesses would value a general "IT Support Certification" from Google, because most businesses aren't using Google's platform.

Google certs for G Suite and such tend to be worth it in the education space where Chromebooks for all have taken over.
